Constructed from high density polyethylene, the 6 inch Gray fitness step was made to be light weight and very durable. Designed for schools, YMCAs, recreational facilities, and commercial gyms. Rounded corners reduce the risk of injury from rough edges, while a non-skid bottom keeps the step in place. The non-slip top was designed with a dimpled surface for exceptional user safety. Light weight, safe, and easy to store.Features:
